Description

Technical Field

[0001] The present application relates to the field of network connectors, and in particular to a male connector, a female connector, and a method for locking and unlocking the same. Background Art

[0002] Traditional connectors typically use a knob-type locking mechanism, requiring manual rotation of the locking mechanism to secure the male and female connectors. However, this type of mechanism has significant drawbacks in practical applications: First, the knob requires two hands to operate and has directional limitations, making it extremely inconvenient during emergency plugging and unplugging or in confined spaces. Second, the threaded mating parts of the rotating mechanism are prone to wear due to frequent operation, resulting in a decrease in locking force or even failure. Furthermore, in vibrating stage equipment or outdoor environments with large temperature differences, the metal knob structure is susceptible to thermal expansion and contraction or mechanical shock, causing the connection to loosen or even accidentally disconnect.

[0003] To improve the above problems, some improvement schemes have been proposed in the prior art. For example, Chinese patent CN212380657U discloses a push-to-rotate plug-in electrical connector, which achieves plug locking by rotating the movable part and the fixed part, and introduces a button-type unlocking mechanism. Although this scheme simplifies the operation process to a certain extent, its locking mechanism still relies on the coordinated movement of multiple parts, has a complex structure and has the following shortcomings: (1) The cooperation between the locking protrusion and the locking groove requires precise rotation angle control, and the assembly tolerance requirements are strict, resulting in increased manufacturing costs; (2) The friction surface is prone to dust accumulation or oxidation during rotation, and is prone to jamming after long-term use; (3) Whether locking or unlocking, the user needs to cooperate with both hands: when locking, one hand needs to hold the male plug and the other hand needs to rotate the movable part to complete the connection; when unlocking, one hand needs to press the button and the other hand needs to perform the plug-in and unplug action. This type of design has low operating efficiency in narrow spaces, high-altitude operations, or scenarios where rapid connection switching is required, and one hand cannot complete the operation independently, which seriously limits the adaptability of application scenarios. Summary of the Invention

[0004] The purpose of this application is to provide a connector male head, female socket, and a method for locking and unlocking the same, which can independently complete the locking and unlocking actions through single-handed operation while ensuring the reliability and durability of the connection in complex environments.

[0005] In order to achieve the above objectives, this application provides the following technical solutions:

[0006] and a locking mechanism adapted to engage a locking cam of the connector body when the locking cam is engaged with the locking cam, wherein the locking cam is engaged with the locking cam and the locking cam is engaged with the locking cam to limit the relative separation of the male head and the female head, thereby achieving locking.

[0007] The beneficial effects are:

[0008] (1) This application uses the compression energy storage and release mechanism of the elastic part, combined with the sliding design of the pressing part, so that the user can complete the locking and unlocking actions with just one hand. When locking, the locking block of the mother seat automatically enters the locking groove through the avoidance groove, and the elastic part drives the lock hook and the lock block to form a self-locking; when unlocking, a single press can release the lock hook, without the need for the other hand to assist in fixing or applying force, greatly improving the operating efficiency. It is especially suitable for small spaces, high-altitude operations, or scenes that require quick plugging and unplugging.

[0009] (2) The locking mechanism of the present application consists only of a pressing member, an elastic member, and a sliding groove, eliminating the complex gear, thread, or moving part matching structure required by traditional rotary locking. This reduces the number of parts and assembly tolerance requirements, thereby lowering manufacturing costs. Furthermore, the sliding design avoids component wear caused by rotational friction, thereby extending service life.

[0010] (3) The locking groove and the lock hook of the present application adopt a one-way sliding locking mechanism without an open rotation gap, which can effectively prevent dust and liquid from entering the internal structure and avoid jamming or failure due to contamination.

[0011] Furthermore, the lateral surface of the pressing member along the sliding direction is provided with a limiting protrusion extending outward, and the first mounting portion is provided with a limiting groove slidingly engaged with the limiting protrusion, and the limiting groove extends along the moving direction of the pressing member.

[0012] Furthermore, the elastic member is a spring, and a limiting column is provided on one side of the pressing member corresponding to the elastic member.

[0013] Furthermore, the inner cavity of the first shell is provided with a limiting portion, and the limiting portion includes a first limiting groove and a second limiting groove. The first limiting groove is used to cooperate with the spring piece of the crystal head to limit the backward movement of the crystal head, and the second limiting groove is used to cooperate with the bottom step of the crystal head base to limit the forward movement of the crystal head.

[0014] Furthermore, the front end of the first shell is provided with a first pair of slots for plugging and mating with the connector female socket, and the inner side of the top wall of the first pair of slots is provided with a first anti-foolproof plane extending along the plug-in direction; the first anti-foolproof plane is used to cooperate with the corresponding anti-foolproof structure of the female socket to limit the correct plug-in direction of the male head and the female socket.

[0015] Furthermore, the first shell has opposite top wall, bottom wall and left and right side walls, the slide groove is arranged near the top, and the opening of the slide groove faces the left side wall or the right side wall, rather than the outer surface of the top wall.

[0016] The present application also proposes a connector female socket, comprising a second shell, a second pair of slots being provided at the front end of the second shell; metal springs being provided on the side walls of the second pair of slots, and the metal springs being used to elastically contact the conductive terminals of the male head; a second anti-foolproofing plane extending along the plug-in direction is provided in the second pair of slots, and the second anti-foolproofing plane corresponds to the first anti-foolproofing plane of the male head to limit the only correct plug-in direction between the male head and the female socket to prevent reverse insertion; a locking block is provided on the second anti-foolproofing plane, and the locking block is used to engage with the locking hook of the connector male head to achieve locking.

[0017] The beneficial effect is that the anti-misturbance flats on the female and male connectors, as well as the locking block and hook structure, create a dual anti-mismated insertion and self-locking mechanism. During insertion, the anti-misturbance flats first guide the male connector into correct alignment, and the locking block then automatically enters the locking groove to complete the mechanical interlock. The entire process requires no additional user intervention, achieving a simplified "insert and lock" operation experience. This coordinated design simplifies the structure while balancing connection reliability and operational efficiency.

[0018] Furthermore, at least one grounding guide spring extending along the plugging direction is respectively provided on the left and right inner walls of the second pair of slots.

[0019] Furthermore, the grounding guide spring comprises a fixing portion fixedly connected to the inner wall of the second pair of slots, and an elastic contact portion obliquely extending toward the center of the second pair of slots;

[0020] The elastic contact portion is used to elastically contact the outer metal shell of the male crystal plug to achieve the grounding function; the inclination angle of the grounding guide spring forms a guiding slope for guiding the male plug to be inserted into the second pair of slots.

[0021] The present application also provides a method for locking and unlocking a male connector and a female connector, wherein the male connector includes a locking mechanism, the locking mechanism including a pressing member and an elastic member, wherein when the elastic member is in a natural state, the pressing member is located in an initial position of a slide groove;

[0022] The method comprises: a locking step and an unlocking step;

[0023] The locking step includes: driving the pressing member to move along the sliding groove in a first direction by an external force, driving the locking hook to leave the first avoiding groove, and the elastic member is compressed and stores elastic potential energy;

[0024] Insert the male connector into the female connector along the plugging direction, so that the locking block of the female connector passes through the first avoidance groove and enters the locking groove of the pressing member;

[0025] When the external force is removed, the elastic member releases potential energy and drives the pressing member to move along the slide groove in the second direction, so that the lock hook and the lock block form an irreversible engagement, limiting the axial separation of the male head and the female seat, thereby achieving locking;

[0026] The unlocking step includes: driving the pressing member to move along the sliding groove in the first direction again by an external force, so as to drive the lock hook to disengage from the locking block, and the elastic member is compressed again;

[0027] Pull the male connector out of the female connector along the plugging direction, so that the locking block exits the locking groove;

[0028] When the external force is removed, the elastic member releases the potential energy and drives the pressing member to return to the initial position along the sliding groove in the second direction.

[0029] The beneficial effects of this application are as follows: Through the "press-insert-release" locking steps and the "press-pull-release" unlocking steps, the user can complete the entire operation with just one hand. When locking, the pressing part is pressed and directly inserted into the female socket, and the elastic part automatically drives the locking hook and the locking block to complete the locking; when unlocking, the male plug can be pulled out with a single press, without the need for rotation, twisting or other complex movements, which greatly reduces the complexity of operation and is particularly suitable for emergency plugging and unplugging or one-handed operation scenarios.

[0046] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0047] Throughout the description of this application, it should be understood that the terms "upper," "lower," "left," and "right," etc., are used solely to facilitate description and simplify the description of this application. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. In particular, in the claims, when the term "upper" follows a noun, it should be understood that the entire interior and exterior surfaces of the structure referred to by the noun meet the definition of "upper."

[0048] The following is a detailed description of the specific implementation methods, structures, features and functions provided by this application in conjunction with the accompanying drawings and preferred embodiments.

[0049] like Figures 1 to 3 As shown, a connector includes a male connector 100 and a female connector 200. When the male connector 100 and the female connector 200 are mated, the locking hook 1213 of the male connector 100 and the locking block 214 of the female connector 200 form a snap fit to prevent the relative separation between the two, thus achieving a locking function. The male connector 100 is equipped with a variety of docking connectors, such as RJ45 connectors and USB ports; the female connector 200 is equipped with docking sockets that match these docking connectors. When the male connector and the female socket are docked, the docking connector and the docking socket achieve electrical or signal connection.

[0050] like Figure 4 and Figure 5As shown, the present application proposes a connector male head 100, including a first shell 110 and a locking mechanism 120; the locking mechanism 120 can be slidably installed in the slide groove 1111 of the first mounting portion 111 of the first shell 110, and the locking mechanism 120 includes a pressing member 121 and an elastic member 122, one end of the elastic member 122 abuts against one end G1 of the pressing member 121, and the other end abuts against the inner wall D1 of the slide groove 1111, and the elastic member 122 is in a compressed state to provide a driving force to move the pressing member 121 along the extension direction F of the slide groove 1111.

[0051] like Figure 6 and Figure 7 As shown, a locking groove 1211 is provided at the bottom of the pressing member 121, and the locking groove 1211 has an entrance 1212, and the side of the entrance 1212 extends to form a locking hook 1213; the first mounting portion 111 is provided with a first avoidance groove 1112, and the first avoidance groove 1112 corresponds to the entrance 1212, so as to cooperate with the locking block 214 of the connector socket 200; when the locking block 214 of the connector socket 200 enters the locking groove 1211 through the entrance 1212, the elastic member 122 drives the pressing member 121 to move toward the outer end of the slide groove 1111, so that the locking hook 1213 and the locking block 214 form a snap fit to limit the relative separation of the male head and the female socket, thereby achieving locking.

[0052] like Figure 7 As shown, in one embodiment, the lateral surface G2 of the pressing member 121 along the sliding direction is provided with an outwardly extending limiting protrusion 1214, and the first mounting portion 111 is provided with a limiting groove 1113 that slidably engages with the limiting protrusion 1214. The limiting groove 1113 extends along the moving direction of the pressing member 121. The limiting protrusion 1214 extends outward and engages within the limiting groove 1113, forming an axial limiting structure. Even if the elastic member 122 is in a compressed state or subjected to external force, it can prevent the pressing member 121 from falling off the mounting portion, thereby ensuring the structural integrity of the locking mechanism 120.

[0053] When the elastic member 122 drives the pressing member 121 to return outward, the limiting protrusion 1214 slides to the end in the limiting groove 1113 and abuts against the end of the groove to prevent the pressing member 121 from excessively displacing and separating from the housing.

[0054] like Figure 6 As shown, the side of the limiting protrusion 1214 corresponding to the pressing direction of the pressing member 121 is provided with an inclined surface G3, which facilitates the insertion of the pressing member 121 into the sliding groove 1111. The gradual transition structure of the inclined surface can reduce the contact resistance between the protrusion and the groove. Even if there is a slight position deviation or processing tolerance, the pressing member 121 can still be smoothly inserted into the limiting groove 1113 by sliding on the inclined surface, avoiding structural damage (such as deformation of the protrusion and wear of the groove) caused by forced assembly.

[0055] like Figure 6 As shown, in one embodiment, the elastic member 122 is a spring, and a limiting post 1215 is provided on one side of the pressing member 121 corresponding to the elastic member 122. The limiting post 1215 provides an axial positioning reference for the spring. The end of the limiting post 1215 can be inserted into the inner hole of the spring to ensure that one end of the spring is stably fixed to the pressing member 121, preventing radial displacement or separation of the spring during compression / reset, and ensuring stable transmission of the elastic force.

[0056] like Figure 8 As shown, in one embodiment, the inner cavity of the first housing 110 is provided with a limiting portion 112. The limiting portion 112 includes a first limiting groove 1121 and a second limiting groove 1122. The first limiting groove 1121 is used to cooperate with the spring clip 310 of the RJ45 connector 300 to limit the rearward movement of the RJ45 connector, and the second limiting groove 1122 is used to cooperate with the bottom step 320 of the RJ45 connector base to limit the forward movement of the RJ45 connector. The engagement of the first limiting groove 1121 with the RJ45 connector spring prevents the RJ45 connector from moving backward (in the direction of the output line) due to vibration or external force during the plugging and unplugging process, ensuring the stability of the terminal contact. The engagement of the second limiting groove 1122 with the base step prevents the RJ45 connector from moving excessively forward (in the plugging direction) during insertion, avoiding deformation of the terminal due to compression or poor contact.

[0057] In high-speed network transmission, tiny displacement may cause signal attenuation. The double limit can fix the crystal head in the optimal contact position.

[0058] like Figure 7 As shown, in one embodiment, the front end of the first housing 110 is provided with a first pair of slots 113 for mating with the connector receptacle 200. A first foolproofing surface 1131 extending in the mating direction is provided on the inner side of the top wall of the first pair of slots 113. This first foolproofing surface 1131 is designed to mate with a corresponding foolproofing structure on the receptacle to define the correct mating orientation between the male and female connectors. By providing these foolproofing surfaces on the inner side of the top wall of the first pair of slots 113, extending in the mating direction, the male and female connectors can be quickly and accurately mated, while also preventing damage to the terminals due to mis-mating.

[0059] like Figure 7 As shown, in one embodiment, the first shell 110 has relative top wall S1, bottom wall S2, left side wall S3 and right side wall S4, and the slide groove 1111 is arranged near the top, and the opening D2 of the slide groove 1111 is toward the left side wall or the right side wall (i.e., the horizontal direction), rather than toward the outer surface of the top wall (vertical upward direction).

[0060] The horizontal opening forces dust and liquids (such as splashed water) to overcome gravity or flow horizontally to enter the chute 1111, while the top wall itself forms a barrier, reducing the probability of contaminants falling directly in. If the opening is facing upward, dust / liquids can fall directly vertically into the chute 1111, increasing the risk of stagnation.

[0061] The horizontal opening direction is more consistent with the direction of force applied by the user when plugging and unplugging (usually horizontal or slightly tilted), reducing additional angle adjustments and improving operational smoothness. When the user plugs and unplugs with one hand, the finger naturally applies force in the horizontal direction, which is consistent with the opening direction of the slide slot 1111.

[0062] like Figure 7 As shown, in one embodiment, a tail sleeve 130 is provided at the tail of the first shell 110, the outer peripheral surface of the tail of the first shell 110 is provided with a first external thread, the inner cavity wall of the tail sleeve 130 is provided with an internal thread adapted to the first external thread, and the tail sleeve 130 is detachably connected to the tail of the first shell 110 through threaded fitting.

[0063] like Figure 8 As shown, in one embodiment, a first waterproof ring 140 is provided between the mating surface of the tail sleeve 130 and the tail of the first housing 110 , and the waterproof ring is used to seal the connection gap between the two to prevent liquid from entering the interior of the male connector.

[0064] like Figure 8 As shown, in one embodiment, a waterproof rubber sleeve 150 and a tail clip 160 are sequentially arranged in the tail sleeve 130 along the cable insertion direction, the waterproof rubber sleeve 150 is close to the tail of the first shell 110, and the tail clip 160 is located behind the waterproof rubber sleeve 150; Figure 3 As shown, the tail clip 160 includes a plurality of clips 161, and a wedge-shaped mating surface is formed between the outer side of the clips 161 and the inner wall of the tail sleeve 130; when the tail sleeve 130 is tightened to the rear end of the first shell 110, the wedge-shaped surface of the inner wall of the tail sleeve 130 pushes the tail clip 160 to contract radially, thereby clamping the outer sheath of the cable.

[0065] like Figure 8 As shown, in one embodiment, the tail end of the clip 161 of the tail clip 160 extends outward to form an annular flange 162. The outer diameter of the annular flange 162 is larger than the inner diameter of the waterproof rubber sleeve 150, and the annular flange 162 abuts the rear end surface of the waterproof rubber sleeve 150 to limit the rearward displacement of the waterproof rubber sleeve 150 along the cable axis. When the tail clip 160 is squeezed and radially contracted by the tail sleeve 130, the annular flange 162 simultaneously retracts toward the center and presses the rear end surface of the waterproof rubber sleeve 150.

[0066] like Figure 8 As shown, in one embodiment, a limiting sleeve 170 arranged axially is further provided in the first shell 110. The limiting sleeve 170 is located between the waterproof rubber sleeve 150 and the crystal head, with its front end face abutting against the rear end of the crystal head, and its rear end face abutting against the front end face of the waterproof rubber sleeve 150, so as to form an axial limit for both.

[0067] like Figure 9 and Figure 10As shown, the present application also proposes a connector female socket 200, including a second shell 210, and a second pair of slots 211 is provided at the front end of the second shell 210; the side walls of the second pair of slots 211 are provided with metal springs 212, and the metal springs 212 are used to elastically contact with the conductive terminals of the male head; a second anti-foolproofing plane 213 extending along the plug-in direction is provided in the second pair of slots 211, and the second anti-foolproofing plane 213 corresponds to the first anti-foolproofing plane 1131 of the male head to limit the only correct plug-in direction between the male head and the female socket to prevent reverse insertion; a locking block 214 is provided on the second anti-foolproofing plane 213, and the locking block 214 is used to engage with the locking hook 1213 of the connector male head 100 to achieve locking.

[0068] The anti-mistakable flats on the female and male connectors, along with the locking block 214 and locking hook 1213, create a dual anti-misinsertion and self-locking mechanism. During insertion, the anti-mistakable flats first guide the male connector into proper alignment, and the locking block 214 then automatically engages the locking groove 1211, completing the mechanical interlock. This entire process requires no additional user intervention, providing a simplified "insert and lock" experience. This coordinated design simplifies the structure while balancing connection reliability and operational efficiency.

[0069] like Figure 10 As shown, in one embodiment, at least one grounding guide spring 215 extending along the plugging direction is respectively provided on the left and right inner walls of the second pair of slots 211 .

[0070] like Figure 10 As shown, in one embodiment, the grounding guide spring 215 includes a fixing portion 2151 fixedly connected to the inner wall of the second pair of slots 211, and an elastic contact portion 2152 extending obliquely toward the center of the second pair of slots;

[0071] The elastic contact portion 2152 is used to elastically contact the outer metal shell of the male plug to achieve the grounding function; the inclination angle of the grounding guide spring 215 forms a guiding slope for guiding the male plug to be inserted into the second pair of slots 211.

[0072] In one embodiment, the grounding guide spring 215 is made of a conductive metal material.

[0073] like Figure 9 As shown, in one embodiment, a dust cover 216 is detachably provided on the outer periphery of the front end of the second shell 210, and the dust cover 216 covers the opening of the second pair of slots 211; the inner side of the dust cover 216 is provided with a sealing flange 2161 adapted to the shape of the second pair of slots 211, which is used to prevent dust and foreign matter from entering the interior of the pair of slots.

[0074] like Figure 10As shown, in one embodiment, a second external thread is provided on the central outer peripheral surface of the second shell 210, and a radially protruding limiting step 217 is provided at the rear end of the second external thread; the second shell 210 also includes a nut 220 and a gasket 230, the nut 220 is threadedly connected to the second external thread, the gasket 230 is arranged between the nut 220 and the device panel, and the limiting step 217 abuts against the inner side of the device panel; when the nut 220 is tightened, the gasket 230 is squeezed and clamped to the device panel, and the limiting step 217 abuts against the inner side of the panel, forming an axial limitation and circumferential anti-rotation for the second shell 210, thereby fixing the second shell 210 on the device panel; wherein, the front end is the end where the second pair of slots 211 is located, and the rear end is the end away from the second pair of slots 211.

[0075] In one embodiment, a second waterproof ring 240 is disposed on the outer circumference of the front end of the second housing 210 .

[0076] In one embodiment, a PCB board 250 is disposed at the rear of the second housing 210 , and the PCB board 250 is connected to the metal spring 212 .

[0077] The present application also provides a method for operating the locking and unlocking of the male connector 100 and the female connector 200. The male connector 100 includes a locking mechanism 120. The locking mechanism 120 includes a pressing member 121 and an elastic member 122. When the elastic member 122 is in a natural state, the pressing member 121 is located in the initial position of the slide groove 1111.

[0078] The method comprises: a locking step and an unlocking step;

[0079] The locking step includes: driving the pressing member 121 along the sliding groove 1111 in the first direction (toward the interior of the first housing 110) by an external force, driving the locking hook 1213 to leave the first avoiding groove 1112, and the elastic member 122 is compressed and stores elastic potential energy;

[0080] Insert the male connector into the female connector along the plugging direction, so that the locking block 214 of the female connector passes through the first avoidance groove 1112 and enters the locking groove 1211 of the pressing member 121;

[0081] When the external force is removed, the elastic member 122 releases its potential energy and drives the pressing member 121 to move along the sliding groove 1111 in the second direction (toward the outside of the first housing 110), so that the locking hook 1213 and the locking block 214 form an irreversible engagement, limiting the axial separation of the male connector and the female connector, thereby achieving locking.

[0082] The unlocking step includes: using an external force to drive the pressing member 121 to move along the sliding groove 1111 in the first direction again, driving the locking hook 1213 to disengage from the locking block 214, and the elastic member 122 is compressed again;

[0083] Pull the male connector out of the female connector along the plugging direction, so that the locking block 214 exits the locking groove 1211;

[0084] When the external force is removed, the elastic member 122 releases the potential energy and drives the pressing member 121 to return to the initial position along the sliding groove 1111 in the second direction.

[0085] This application uses a "press-insert-release" locking procedure and a "press-pull-release" unlocking procedure, allowing users to complete the entire operation with just one hand. When locking, pressing the pressing member 121 directly inserts the female socket, and the elastic member 122 automatically drives the locking hook 1213 and the locking block 214 to complete the lock. When unlocking, a single press can pull out the male connector without rotating, twisting, or other complex movements, greatly reducing operational complexity. It is especially suitable for emergency plugging and unplugging or one-handed operation scenarios.

[0086] The embodiments described above are only preferred implementation modes of the present application. It should be pointed out that ordinary technicians in this technical field can make several improvements and replacements without departing from the technical principles of the present application. These improvements and replacements should also be regarded as the scope of protection of the present application.
